REMOVABLE BRUSH HEAD.

Application filed September 30, 1925. Serial No. 59,666.

This invention relates to brushes and aims to provide novel meanswhereby a brush head may be removably mounted in such a way that thesame may be readily and easily removed so that larger or smaller brushesmay be substituted therefor at the Will of the operator. v

With the foregoing and other objects in view which will appear as thedescription proceeds. the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed. may be made Within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is a side elevational view illustrating a brush constructed inaccordance with the invention. I

Figure 2 is an enlarged elevational view of the brush and its supportinghousing.

Figure 3 is a vertical sectional view through the brush and its housing.

Figure 4 is a sectional view taken on line 44 of Figure 3.

Figure 5 is. a sectional view through the 0 connecting drum.

Referring to the drawings in detail, the device includes a connectingdrum indicated generally by the reference character 5, and as shown, theconnecting drum is provided with a projecting bearing housing 6 in whichthe bearings 7 are mounted, the bearings being held within the bearinghousing by means of the retainer 8, and plate 8'.

The power shaft is shown at 9 and is provided with a squared opening inone end thereof to receive one end of the shaft 10 which is also fittedin a squared opening formed in one end of the connecting sleeve 11, theopposite end of the sleeve being provided with a squared socket 12 forthe reception of the armature shaft of the motor to which the device isto be secured.

The power shaft 9 is secured within the member 11 by means of the cotterpin 13 which extends through a suitable opening formed in the shaft 10.

Mounted on the outer end of the flexible shaft 14 is a pinion 15 whichmeshes with the gear 16 formed at the u per end of the sleeve 17, theopposite en of the sleeve being connected with the support 18 which isheld in position by means of the bolt 18 shown as extending through thesupport, and through the inner bearing member 19'. The support 18 alsocarries the connecting member 19 that is provided with outwardlyextended flanges 2O curved to conform to the curvatures of the flanges21- that are carried by the brush 22. Thus it will be seen that due tothis construction, the brush 22 may be readily and easily removed fromthe flanges 20, so that brushes of various sizes may be used inconnection with the brush support.

The reference character 23 designates a gear housing, the shape of thesame being such as'to be readily grasped and held by the operator inmoving the brush from place to place during the cleaning operation.

In the use of the device, the device is connected with a suitable motoras described which motor is ada ted to rapidly rotate the flexibleshaft, which in turn transmits rotary motion to the brush support andbrush carried thereby.

I claim In adevice of the character described, a brush support includingoutwardly extended curved flanges, a brush including a head, outwardlycurved flanges extending from the head and adapted to be positioned overthe first mentioned flanges to remov- .ably secure the brush head to thebrush support.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature.
